The amount of fuel needed to travel to Mars and back depends on various factors such as the spacecraft design, propulsion system, payload weight, and trajectory. For a mission like NASA's Mars Rover, Curiosity, it required around 2000 pounds (900 kg) of fuel for the journey to Mars. The return trip would require a similar amount of fuel.
254 days by the most fuel-efficient orbit, IIRC. Distance doesn't matter as much as travel time, and Mars is pretty close.

The exact amount of fuel needed to travel to Mars and back would depend on the spacecraft design, propulsion system, and mission profile. Estimates suggest that a round trip to Mars would require tens of thousands of gallons of fuel due to the large distance and complex orbital dynamics involved in such a mission.
It would take about 9 years to travel from Earth to Jupiter, assuming a similar speed and trajectory as the trip from Earth to Mars. Jupiter is much farther away from Earth than Mars, so the journey would be significantly longer.
That depends on your fuel mileage.
== == I think that would be 30,000 liters.
10 years
Sounds on Mars haven't been recorded because there isn't much to hear on Mars. The only sounds you would really hear would be wind gusts. Sound would also not travel very well through the thin Martian atmosphere.
if there is water if it is at the right temperature how long it would take us to get their how much fuel we would need in a rocket to get to mars are their any aliens or harmful animal their is their enough oxygen etc.
90000 @ 1$/l with a consume of 9l/100km
Not very much.
